             Suppresses warning message in Penelope PhotoElectric process
             (G4PenelopePhotoElectric and G4PenelopePhotoElectricModel) from
             from G4AtomicTransitionManager appearing for some elements
             (Oxygen ,Fluorine). This is due to the fact that Penelope and
             G4AtomicTransitionManager databases may contain a different number
             of shells. Physics results are unchanged.
             Geant4-DNA processes:
             - Corrected energy limits in G4CrossSectionIonisationBornPartial.
             - Added proton case in G4CrossSectionExcitationMillerGreenPartial
               and added protection for water excitation energy).
             - Added 'kill particle without total energy deposit' feature for
               DNA charge change processes.
             Ion ionisation:
             - Added protections against FPE in G4hLowEnergyLoss
               Fixes problem report #953 (also report in Hypernews EM forum #893).
             - Fixed bug for ICRU73 ion model.

             Correction for G4PenelopeComptonModel: now the cross section table 
             calculated by the model corresponds to the original FORTRAN-Penelope. 
             The difference was only for compounds materials and below 1 keV, so 
             irrelevant for virtually all applications.

             not sure whether this is correct, since this is old
             code moved from utils/, deprived of any documentation
             and with an evident fortran look. A design review
             is planned to take care of this domain in a proper way.
             Also included an updated version of G4BraggModel
             provided by V.I. due to an interface change: however
             this class is not used anywhere in the package, and is
             retained only for historical reasons; it is candidate to be
             trashed in the next design review.

             Various fixes to the DNA processes to allow compilation with
             gcc 3.4.5. Some of the fixes are dummy implementations, or
             do not make sense physically; they should be revised in 
             a future dummy implementation. The present version of the
             DNA processes is meant as a first beta release, and is not
             suitable for physics application yet.

               The vector dimension has been resized from 10 to 100 in order
               to avoid memory corruption errors caused by code in 
               src/G4hLowEnergyIonisation.cc.

               - Processes tested (preliminary test). Protons seems fine
                 while alpha particle total cross section differs from
                 plots in the reference documents
             * G4DNATest upgrade in order to manage the new implemented

24.06.2005   Riccardo Capra, tag emlowen-V07-00-13
             * Changes to G4(*)EMDataSet classes according to the design
               iteration:
              - LoadData is now a public virtual method
              - SaveData is a new method that allows data saving in the same
                format of LoadData.
              - Constructors with the filename cannot be used anymore. They
                are substituted with constructors that generates an empty
                data set
              - Energies and Data can be set after de construction with
                the new SetEnergiesData

             * Changes to G4VLowEnergyDiscretePhotonProcess in order to
               inherit from G4VLowEnergyTestableDiscreteProcess.
               - GetMeanFreePath and PostStepDoIt methods of all discrete
                 processes made inherit from G4VLowEnergyTestableDiscreteProcess 
                 could be (partially) tested with a unique testing code now.
             
             * DNA code changed according to the design iteration tha now
               uses templated classes
               
             * Code builds and links the test codes unde Linux.
               - G4(*)EMDataSet and DNA classes test are still in progress
               - Some minor changes could be done to the structures used to
                 configure the policy-based processes

18.09.2000 - MGP, tag emlowen-V02-00-10
             Improvements to the readability of the code by V. Ivanchenko

17.09.2000 - MGP, tag emlowen-V02-00-09
             New features on antiproton ionisation by Stephane Chauvie:
             extension of the Quantum Harmonic Oscillator model to
             generic materials, calculation of oscillator strengths for 
             all elements
             Antiproton model also moved to be compliant with the new design
             iteration

16.09.2000 - MGP, tag emlowen-V02-00-08	
             Const cast in G4hLowEnergyIonisation (const G4Material* into
             G4Material*) to convert the previously _good_ LowE code 
             into bad one, but palatable to G4EnergyLossTables, that has 
             various member functions requiring a non-const G4Material* 
	     pointer in the arguments
             This modification was required to avoid compilation errors
             on DEC; it is meant to be temporary
             The affected pointers SHOULD BE REVERTED TO CONST 
             AS SOON AS POSSIBLE, after agreement with the 
             G4EnergyLossTables author

16.09.2000 - MGP, tag emlowen-V02-00-07
	     Fix in G4hICRU49He::StoppingPower - a1 changed into e1 (typo?) 
	     to remove compilation problems on DEC (uninitialized variable)
             Fix in G4hLowEnergyLoss, eliminated two protected variables
             G4Proton* theProton and G4AntiProton* theAntiProton 
             to revove compilation problems on DEC (hiding)

16.09.2000 - MGP, tag emlowen-V02-00-06
